Drum motor (motorised pulley)
Motor and gearbox sealed inside the pulley to drive a belt conveyor directly: compact, low-maintenance, wash-down versions for food, supplied with new conveyors or on its own as a spare.

A drum motor seals the motor and gearbox inside the pulley, which sits at the end of a belt conveyor and drives the belt directly. Compared with an external gear motor it removes drive parts from the side of the conveyor and has no exposed chains or couplings, so it is easier to clean and guard; packaging and logistics conveyors use it widely, and for food the protection class, corrosion resistance, lubricant and contact-material documents are checked separately. Small diameters drive light belt conveyors, large ones wider and heavier belts. It is supplied with new equipment or on its own as a spare.
Typical uses
- Belt conveyors in logistics and parcel handling
- Food, beverage and bakery lines (wash-down type)
- Conveyor sections of packaging, weighing and inspection machines
- Replacing drives on existing conveyors
How to choose
- Belt width, effective tension and wrap angle, which set the diameter and face width
- Belt speed, load and duty cycle, which set power and ratio
- Local mains voltage and frequency
- Whether it is washed down: for food, check protection class, corrosion resistance, lubricant and contact-material documents
When it is not the right choice
- High-power heavy-duty conveying such as long bulk conveyors: outside this range
- Frequent speed changes and positioning: confirm the drive and encoder set-up first
Key figures
| Diameter | Published model examples: small about Ø50–76 mm, common about Ø110–270 mm |
|---|---|
| Power | Published model examples: small about 80–100 W, common about 0.12–2.2 kW |
| Face width | Set by belt width |
| Supply | To local mains, e.g. 400 V 50 Hz |
| Options | Lagging, stainless wash-down type, built-in encoder or brake (by model) |
Figures are typical configuration ranges; exact specifications are set per project.
Options
- Lagging for more grip
- Stainless shell and food-grade lubricant
- Built-in encoder or brake
- Matching frequency inverter
Scope of supply
